我们调查的可能性映射大规模的反气旋涡，导致全球斜压不稳定，作为行星形成的前体在原行星盘与计划中的阿塔卡马大型毫米波阵列（阿尔马）。在三维辐射传输模拟的基础上，导出了流体动力学计算圆盘的图像，为阿尔马的模拟提供了基础。我们发现，阿尔马将能够跟踪理论上预测的大规模反气旋涡旋，因此，将允许测试现有的模型，这个非常早期的行星形成阶段的拱星盘。
We investigate the possibility of mapping large-scale anticyclonic vortices, resulting from a global baroclinic instability, as precursors of planet formation in protoplanetary disks with the planned Atacama Large Millimeter Array (ALMA). On the basis of three-dimensional radiative transfer simulations, images of a hydrodynamically calculated disk are derived that provide the basis for the simulation of ALMA. We find that ALMA will be able to trace the theoretically predicted large-scale anticyclonic vortex and will therefore allow testing of existing models of this very early stage of planet formation in circumstellar disks.
